I am almost done with an observership and I was wondering how to go about asking for the letter of recommendation. I have read online that you should leave self addressed envelopes or leave the envelopes directly addressed to the program where you will be applying. I obviously live abroad so I can't really leave self addressed envelopes and also I also still have 2 years left before I am done with medical school and start applying for residency. What can I do? Ask for a print copy and scan in in the future to upload it to my application later? Seems less official to me...
